不同海域中国花鲈营养成分的比较研究

Comparative Analysis of Nutritonal Components of Lateolabrax sp. in Different Sea Areas

对威海、舟山、福州、厦门、北海 5个沿海野生群体的中国花鲈的肌肉进行了营养成分的比较研究。结果表明 ,它们都富含蛋白质 ,且必需的氨基酸种类齐全 ,配比合理 ;富含不饱和脂肪酸和微量元素 ;蛋白质、氨基酸含量具有由北向南逐渐升高的趋势 ,总脂质含量反之 ;不饱和脂肪酸相对含量也由北向南逐渐升高的趋势 ,南方多不饱和脂肪酸含量高于单不饱和脂肪酸含量 ,北方则反之。

Comparative analysis is made of the mutritional components of the muscles of Lateolabrax sp. from different sea areas. The results show that all the mascles contain protein, necessary amino acids, unsaturated fatty acids and mineral trace elements. The protein, amino acid, and unsaturated fatty acids increase from north to south. The content of poly-unsaturated fatty acids is higher than that of single unsaturated fatty acids in the south and the situation is the opposite in the north.
